The suspect was charged with two counts of murder and awaiting arraignment at criminal court in Hempstead.

Nassau County police said that Rose Ormejuste, the suspect's mom and Bob Ormejuste's wife, was missing. They were also searching for Guerby Ormejuste's gray 1998 Lexus ES 300.

"We believe there's a connection with the missing mother in that car," said Repalone. "The defendant is not saying anything about the mother or a motive. We're concerned for her well being."

Nassau Police investigate the scene of a reported double murder in an Elmont Long Island home.

Helicopters and license plate readers, among other tools, are being used to find the Lexus, Repalone added. Its New York license plate is CEF8130.

Cops made the grisly discovery after Guerby Ormejuste, 30, mysteriously missed work at the Eric M. Taylor Center on Rikers Island for two days. He was found in the home's kitchen about 4:20 a.m.

His father's body was discovered a short time later in the basement.

The gun was recovered inside of the home, police said.

Guerby Oremjuste, who was on duty when a female officer tried to get a peek at celebrity/rap star Lil Wayne, had been a correction officer since March 2007.

"The Department of Correction and all of its officers and staff are saddened by this family tragedy, and we mourn his loss," the department said in a prepared statement. "He and his family are in our thoughts and prayers."
